Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of prefabricated building, in particular to a multi-rib sandwiched combined arched cover plate and arched pipe gallery. BACKGROUND

[0002] With the development of modern industrial technology, prefabricated buildings gradually replace the existing ordinary building system in the existing technology with the advantages of fast construction speed, less dependence on weather conditions, and labor saving.

[0003] For underground squares, underground passages or comprehensive pipe galleries, most of them adopt arched top design. Since most of them are located underground, there is soil or road at the upper end, which causes certain load on the top. The arched top design is to disperse the pressure and avoid collapse. However, most of the existing arched top is cast in situ or built by hollow bricks, which is high in construction difficulty, construction cost and construction time. SUMMARY

[0004] Therefore, in order to solve the problem of high construction cost and difficulty of the pipe gallery in the prior art, the present application provides a multi-rib sandwiched combined arched cover plate and arched pipe gallery.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical scheme: A multi-rib sandwiched combined arched cover plate comprises a horizontally curved bottom plate, a plurality of linearly poured longitudinal ribs arranged in a circular array on the outer circle of the bottom plate, a plurality of arc-shaped filling blocks arranged on the outer circle of the bottom plate between adjacent two linearly poured longitudinal ribs, and arc-shaped poured horizontal ribs arranged between adjacent two filling blocks. An arc-shaped upper flange is arranged on the upper surface of the linearly poured longitudinal rib, and the upper surfaces of a plurality of arc-shaped upper flanges are located on the same circular surface and are coaxially arranged with the bottom plate.

[0006] As a further improvement of the above-mentioned technical scheme: As an optimization scheme of the above-mentioned technical scheme, arc-shaped side flanges are arranged on the outer sides of the linearly poured longitudinal ribs on both sides.

[0007] As an optimization scheme of the above-mentioned technical scheme, the arc-shaped filling blocks and the upper surfaces of the linearly poured longitudinal ribs are located on the same circular surface.

[0008] As an optimization scheme of the above-mentioned technical scheme, a plurality of arc-shaped transverse communication steels are transversely arranged on the plurality of arc-shaped upper flanges.

[0009] As an optimization scheme of the above-mentioned technical scheme, the lower surface of the upper flange is in contact with the upper surfaces of the arc-shaped filling blocks and the arc-shaped poured horizontal ribs.

[0010] As the optimization scheme of the above technical scheme, the arc-shaped filling block is any one of an arc-shaped hollow block with an opening facing downward, an arc-shaped sandwich block with an opening facing downward or an arc-shaped light strip-shaped slot plate.

[0011] As the optimization scheme of the above technical scheme, the bottom plate adopts a TRC bottom plate.

[0012] The application also provides a multi-rib sandwiched superimposed arched pipe gallery formed by splicing the multi-rib sandwiched superimposed arched cover plates.

[0013] Compared with the prior art, the application has the following beneficial effects: Compared with the arched top of the existing pipe gallery, the application adopts a prefabricated assembly structure, converts a large amount of on-site pouring operation into factory production, greatly reduces the on-site formwork, pouring and maintenance time, significantly reduces the construction difficulty, shortens the construction period and improves the construction efficiency.

[0014] The use of the strip-shaped filling block can effectively reduce the self-weight of the cover plate while ensuring the structural strength, is conducive to transportation and hoisting, reduces the requirement for the lower support structure, reduces the amount of concrete used by the use of the filling block and reduces the material cost and structural self-weight.

[0015] The cover plate of the application is designed for the arched top of an underground pipe gallery, passage or square, can form arched pipe galleries with different spans and lengths by splicing, has high standardization and wide application range. BRIEF DESCRIPTION OF DRAWINGS

In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0021] Embodiment 1 As shown in the accompanying Figure 1 The technical scheme in this embodiment is mainly used for the construction of the arched top of the underground passage, underground square and comprehensive pipe gallery, and the specific structure is as follows: The bottom plate 1 is a main connecting member, which is transversely curved, and in order to reduce the thickness and weight of the whole, the TRC bottom plate 1 is adopted, which greatly reduces the weight and thickness while ensuring the compression resistance; A plurality of linear pouring longitudinal ribs 2 in transverse circular array are arranged on the bottom plate 1 in the transverse direction, a plurality of arc-shaped filling blocks 3 are arranged longitudinally between two adjacent linear pouring longitudinal ribs 2, and arc-shaped pouring transverse ribs 4 are arranged on the outer sides of two adjacent arc-shaped filling blocks 3 and the outermost arc-shaped filling block 3; The upper surfaces of the arc-shaped filling blocks 3, the linear pouring longitudinal ribs 2 and the arc-shaped pouring transverse ribs 4 are located on the same circular surface, and the circular surface is coaxially arranged with the bottom plate 1; An arc-shaped side wing edge 6 is arranged on the bottom plate 1 outside the two linear pouring longitudinal ribs 2, which is used for lapping on the pipe gallery side wall plate.

[0022] At the same time, an arc-shaped upper wing edge 5 is arranged on the upper end of the linear pouring longitudinal rib 2, the outer circular surface of a plurality of arc-shaped upper wing edges 5 is also located on the same circular surface, and the circular surface is coaxially arranged with the bottom plate 1, so as to avoid the occurrence of cracking during hoisting and the dispersion of load force during use, and therefore a plurality of parallel distributed through arc-shaped transverse communication steel bars 7 are arranged in the transverse direction of the arc-shaped upper wing edge 5.

[0023] Meanwhile, the settings for the arc-shaped fill block 3 include the following cases: 1. As attached Figure 1 As shown, the arc-shaped hollow block has its opening facing downwards. An air insulation layer is formed between the opening of the arc-shaped hollow block and the bottom plate 1, which helps to increase the insulation effect and is suitable for the arched top of the passage with a smaller load-bearing requirement. 2. As attached Figure 2 As shown, the arc-shaped sandwich block has its opening facing downwards. Compared to the arc-shaped hollow block, its opening slot is filled with a filler block (such as a foam filler block). It is suitable for arched passageways with general load-bearing requirements, such as where only pedestrians walk on the top. 3. As attached Figure 3 As shown, this is an arc-shaped lightweight strip grooved slab, suitable for underground passages at the bottom of roads, and for passage arches with high load-bearing capacity requirements.

[0024] Example 2 This embodiment 2 is a pipe gallery formed by longitudinally splicing the closely ribbed sandwich arched cover plates of embodiment 1. Alternatively, multiple longitudinally spliced ​​pipe galleries can be horizontally spliced ​​to form multiple arched pipe galleries.
